The mature form of l-phenylalanine oxidase (PAOpt) from Pseudomonas sp. P-501 was generated and activated by the proteolytic cleavage of a noncatalytic proenzyme (proPAO). The crystal structures of proPAO, PAOpt, and the PAOpt-o-amino benzoate (AB) complex were determined at 1.7, 1.25, and 1.35A resolutions, respectively. The structure of proPAO suggests(More)
The mature form of L-Phe oxidase of Pseudomonas sp. P-501 (PAOpt) catalyzes the oxygenative decarboxylation of L-Phe and the oxidative deamination of L-Met, and is highly specific for L-Phe. The crystal structures of PAOpt individually complexed with L-Phe and L-Met and the properties of the active site mutants were investigated to clarify the structural(More)
The sarcosine oxidase gene and nearby genes from Corynebacterium sp. U-96 were determined. The genes for serine hydroxymethyltransferase, the beta, delta, alpha, and gamma subunits of sarcosine oxidase, serine dehydratase, and 10-formyltetrahydrofolate hydrolase are arranged in this order. This suggests that the bacteria contain a cluster of genes for the(More)
The nucleotide sequence encoding L-phenylalanine oxidase (deaminating and decarboxylating) (PAO) from Pseudomonas sp. P-501 was determined. The open reading frame is arranged in the order of prosequence, alpha subunit, dipeptide and beta subunit from the 5'- to 3'-end. Expression of the gene in Escherichia coli showed that without the prosequence, PAO is(More)
